Orgasms are one of the most pleasurable experiences that any human being can have.

However, have you ever wondered what happens inside your body during an orgasm? There’s plenty of scientific evidence behind this topic that can help you understand what’s going on. In this article, we’ll be discussing the physiological changes that occur in our bodies during an orgasm.

What is an Orgasm?

Before we get into the details, let’s start with the basic definition. An orgasm is a physical reflex that happens during sexual activity when the body releases a burst of endorphins.

Endorphins are chemicals that are produced by the body and help to reduce pain and increase pleasure.

Physiological Changes During an Orgasm

When we experience an orgasm, many changes in our body occur. Let’s take a look at some of these changes in detail:.

The Brain

An orgasmic experience begins in the brain. Sexual stimulation activates the reward centers in the brain, including the amygdala, hippocampus, and nucleus accumbens.

These are the areas of the brain that are responsible for the release of endorphins, dopamine, and serotonin – the chemicals that produce intense feelings of pleasure and satisfaction during an orgasm.

The Heart Rate

The heart rate increases during sexual arousal, and it continues to grow during orgasm. It’s the equivalent of mild to moderate exercise when it comes to heart rate.

The average heart rate during sexual activity is 70-80 beats per minute, but it can increase up to 180 beats per minute during orgasm.

The Breathing

A person’s breathing becomes more erratic and shallow during sexual activity, and it reaches its peak during orgasm. This can happen in both men and women.

It’s not uncommon for people to hold their breath during orgasm, which can result in hyperventilation and lightheadedness.

The Muscles

A lot of muscles contract during an orgasm, including the pelvic floor muscles, the anal sphincter, and the uterus. These are the muscles that are responsible for the spasm and contractions that we feel during orgasm.

In men, the muscles of the penis contract to expel semen, while in women, the uterus contracts.

The Skin

During sexual arousal, blood vessels dilate throughout the body, causing an increase in blood flow to the skin. This is why people can appear flushed or blush during sexual activity.

During orgasm, the skin can feel hypersensitive, and some people might experience a mild rash or hives due to the increase in blood flow.

The Reproductive System

Orgasm triggers the release of a cocktail of hormones from the brain, including oxytocin, which helps to facilitate bonding between partners. In men, the prostate gland and seminal vesicles release fluid that mixes with sperm to form semen.

Contrary to popular belief, women also ejaculate during orgasm. The fluid comes from the Skene’s glands located near the bladder.

The Nervous System

During sexual arousal and orgasm, our nervous system is on high alert. This provides us with heightened sensations and sharp reflexes. It’s why some people experience involuntary movements or spasms during orgasm.

Orgasms and Health Benefits

Orgasms have been shown to have numerous health benefits, both physical and mental. Here are some of the health benefits of orgasms:.

Reduces Stress

Orgasms release endorphins, which help to reduce stress levels. It also increases oxytocin, which promotes relaxation and bonding, making you feel calm and relaxed.

Improves Sleep Quality

Orgasms trigger the release of prolactin, which is a hormone that helps people sleep better. Men can also experience a refractory period after orgasm, making them feel more relaxed and more likely to fall asleep.

Burns Calories

Sexual activity and orgasms can help burn up to 85 calories per session. It’s not the primary reason to engage in sexual activity, but it’s a good bonus benefit.

Relieves Pain

The endorphins that are released during an orgasm are natural painkillers, which help to reduce pain levels. It helps with pain related to menstruation, arthritis, and post-surgical pain.

Conclusion

Orgasms might seem like just pure pleasure. However, they’re actual physical reactions that occur in our body, which affects our physical health and well-being.

Understanding how our bodies respond during sexual arousal and orgasm can help us to make informed and healthy choices in our sexual lives.
